A quadratic linear equation appeared on the draft test paper. The time-traveling girls were so excited that they thought they had met a fellow countryman. Only I knew that this was a hunting bureau for time-travelers - if you showed modern knowledge, you would be seduced by the emperor into a life-extending medicine. I pretended to be a fool and handed in the paper, becoming the only survivor. After entering the palace, I pretended to be stupid to hide from the murderous emperor, and secretly discovered that he was a puppet of the evil system, and he lived by devouring high-dimensional souls. I teamed up with the murdered Ninth Princess to destroy the system using logical paradoxes, and finally gave up on Ronghua and chose to take her back to modern times.
